| Summary: | Recently, because of
its importance in computer vision and
surveillance systems, object tracking has
progressed rapidly over the last two decades.
Researches on such systems still face several
theoretical and technical problems that badly
impact not only the accuracy of position
measurements but also the continuity of
tracking. In this paper, a novel strategy for
tracking multiple objects using static cameras
is introduced, which can be used to grant a
cheap, easy installation and robust tracking
system. The proposed tracking strategy is based
on scenes captured by a number of static video
cameras. Each camera is attached to a
workstation that analyzes its stream. All
workstations are connected directly to the
tracking server, which harmonizes the system,
collects the data, and creates the output
spatial-tempo database. Our contribution comes
in two issues. The first is to present a new
methodology for transforming the image
coordinates of an object to its real
coordinates. The second is to offer a flexible
event-based object tracking strategy. The
proposed tracking strategy has been tested over
a CAD of soccer game environment. Preliminary
experimental results show the robust performance
of the proposed tracking strategy. |
